It is necessary to develop the one stop system in order to protect our marine environment rapidly from oil spill accident. The purpose of this study is to develop real time database for oil spill prediction modeling and implement real time prediction modelling with ESI and server-client GIS based user interface. The existing oil spill prediction model cannot provide one stop information system for public and government who should protect sea from oil spill accident. The development of multi user based information system permits integrated handling of real time meteorological data from external ftp. A server-client GIS based model is integrated on the basis of real time database and ESI map to provide the result of the oil spill prediction model. End users can access through the client interface and request analysis such as oil spill prediction and GIS functions on the network as their own purpose.

To realize GIS on internet two methods are possible. One is using java language and the other is using window API that interface with internet WWW HTTP protocol. GIS program needs to extract, classify, store in various geospatial data. But WWW HTML are statical and Impossible to input multi points and area selectioning. This study applied JAVA in Web GIS so that may handle various geographic data on internet, communicate interactively GUI interface and present, modify and powered with various means of cartographic visualization

A GIS-RUSLE system has been developed to estimate soil losses from where individual fields on a hillslope using the RUSLE in a GIS environment. The GIS-RUSLE adopts a user interface and a user can use the drop-down menus to define the inputs and get the calculated results. The input data are generated from Arc/Info and ArcView GIS and the factors of the RUSLE are provided from ArcView Avenue. Examples of the GIS-RUSLE applications are presented.

Because the complexity in the development phase of geographic information system, its hard to change its operation or user interface after the development. So we should develop most part of the applied GIS even though previous GIS is almost exist. In other words, reusing the previous system is not easy. Therefore, its required to research reusable GIS for easy construction of applied GIS. This thesis describes design and implementation of web GIS framework which makes applied web GIS development more easy. Framework is software library composed of reusable units such like classes and objects. Proposed web GIS framework Provides basic web GIS functionalities and execution design to web GIS developers. They could extend the framework to build applied web GIS with applied operation and user interface. The development of applied web GIS could be archived by various tools used for general web application development.

Most distributed models have been developed for data interchange between model for hydrological analysis and GIS(Geographic Information System). And some interface systems between them have been developed to operate the model conveniently. This study is about developing integrated system between model and GIS not coupled system based on file interchange or interface system. In this study, HyGIS-GRM which is integrated system between GRM(Grid based Rainfall-runoff Model) which is physically based distributed rainfall-runoff model and HyGIS(Hydro Geographic Information System) have been developed. HyGIS-GRM can carry out all the processes from preparing input data to appling them to model in the same system, and this operation environment can improve the efficiency of running the model and analyzing modeling results. HyGIS-GRM can provide objective modeling environment through establishing the process of integrated operation of GIS and distributed model, and we can obtain fundamental technologies for developing integrated system between GIS and water resources model.

The purpose of this study is to establish the databases of pollutant sources and water quality measurement data by utilizing GIS, and making the user interface for the management of pollutant sources. Yeongsan Estuarine Lake was formed of a huge levee of 4.35 km constructed by an agricultural reclamation project. Water quality of the reservoir has been degraded gradually, which mainly attributes to increase of point and non-point source pollutant loads from the lake's watershed of 33,374.3 $\textrm{km}^2$ into it. Application of GIS to establishment of the database was researched of pint source such as domestic sewage, industrial wastewater, farm wastes, and fishery wastes, and non-pont source such as residence, rice and upland field, and forest runoffs of the watershed of the lake. NT Acr/Info and ArcView were mainly utilized for the database formation. Land use of the watershed using LANDSAT image data was analyzed for non-point source pollutant load estimation. Pollutant loads from the watershed into the reservoir were calculated using the GIS database and BOD, TN, TP load units of point and non-point sources. Total BOD, TN, TP loads into it reached approximately to 141, 715, 2,094 and 4,743 kg/day respectively. The loads can be used as input parameters for water quality predicting model of it. A user-friendly interface program was developed using Dialog Designer and Avenue Script of AcrView, which can perform spatial analysis of point and non-point sources, calculate pollutant inputs from the sources, update attribute data of them, delete and add point sources, identify locations and volumes of water treatment facilities, and examine water quality data of water sampling points.

Recently, as the result of high technology of computer environments. various types of computer applications have been researched and developed. Ana, because of the growth of the mobile device such as PDA, HPC, and location tracking technology such as GPS, various services that is based on personal locations are provided. For these Mobile GIS, there is needed a development of client for Mobile GIS that is considered about the characteristics of mobile device. So, we design and implement client interface for Mobile GIS in this paper.

As semiconductor memory becomes cheaper, the memory capacity of computer system is increasing. Therefore computer system has sufficient memory for a plentiful spatial data. With emerging spatial application required high performance, this paper presents a GIS database system in main memory. Memory residence can provide both functionality and performance for a database management system.

This paper proposes The Efficient method that should design Geosensor model based on object oriented design pattern and implement the Geosensor network interface system using JBuilder. Such as geosensor technology will be to a new research paradigm of GIS which can manage a great quantity of field information by means of constructing the real time remote sensing network. The technology that integrates object oriented design pattern Geosensor interface network with GIS will be necessary elements that satisfy the function of GIS increasing day by day. Therefore, we would like to utilize GoF design pattern in order to change for the better object oriented Geosensor middleware. This paper shall contribute to implementing the optimal Geosensor interface that can develop reusable, modular and modifiable software by using the object oriented design pattern.
